BACKGROUND

1. Field of the Invention

The present invention relates to an automatic transmission holding plateand a wiring unit provided with the same.

2. Description of the Related Art

Conventionally, electrical components such as control components (ROM,etc.) and various sensors and a wiring unit formed by unitizingelectrical wiring for signal transmission among these electricalcomponents or external signal transmission are assembled, for example,into an automatic transmission of an automotive vehicle to control aspeed changing operation. A wiring unit having such a configuration isknown from Japanese Unexamined Patent Publication No. 2010-106946.

SUMMARY OF THE INVENTION

Although an electrical wiring network is built by busbars in the aboveconfiguration, a wiring harness may be used instead of busbars. However,in the case of a wiring harness, wires tend to be lifted in intermediateparts due to necessity to ensure a certain extra length for wiring. Dueto a possibility that the lifted parts interfere with surroundingmembers, a measure is generally taken to fix the wires to aninstallation surface using tie bands.

At a position where the tie band is used, a pair of through holes areopen on the installation surface. On the other hand, as well known, thetie band includes a flexible band portion formed with a plurality oflocking teeth in a sawtooth manner on one surface side and a lockportion formed on one end of the band portion. Further, an insertionopening through which the band portion is inserted with a free end sidein the lead penetrates through the lock portion, and a locking clawcapable of selectively locking the locking tooth is deflectably formedin the lock portion. In the case of tying the wiring harness using sucha tie band, after being inserted through one of the pair of throughholes, the free end of the band portion is turned on the underside ofthe installation surface and inserted through the other through hole.Thereafter, the free end of the band portion is inserted through theinsertion opening and a part pulled out from the lock portion isstrongly pulled. If a certain tightened state is obtained for the wiringharness in this way, a pulling operation is stopped. Then, the lockingtooth and the locking claw are locked at that position and the wiringharness is strongly tied.

As shown in FIG. 11, the lock portion is pulled toward thelater-inserted one of the pair of through holes as the band portion ispulled. Then, the wiring harness is also pulled together in the samedirection as the lock portion is pulled. In the case of FIG. 11(A), thewiring harness WH is pulled to a left side shown. However, in the caseof FIG. 11(B) showing a wrong insertion sequence of the band portionthrough the pair of through holes, the wiring harness WH is pulled to aright side shown. If such a situation occurs, the lock portion and thewiring harness may move out of an originally designed retractable spaceand interfere with surrounding members.

The present invention was completed based on the above situation andaims to provide an automatic transmission holding plate and a wiringunit capable of causing a tie band to pass through a pair of throughholes in a proper insertion sequence.

A holding plate of the present invention is a holding plate mounted inan automatic transmission of an automotive vehicle and configured tohold wires, and characterized in that the holding plate is formed with asupport surface for holding the wires, a pair of through holes, throughwhich a tie band for tying the wires is inserted, is formed on thesupport surface, the through holes are formed to be able to hold thewires in a tied state by allowing a free end side of a band portion ofthe tie band to be successively inserted therethrough and locked to alock portion formed on an opposite end part of the band portion, and thepair of through holes are formed to have mutually different shapes.

A wiring unit of the present invention is characterized by including theholding plate according to the above configuration.

One of the pair of through holes may be formed to be open sideways bycutting a side edge of the support surface. By forming the one of thethrough holes to have an open hole edge, the pair of through holes canbe spaced apart by a long distance as compared with the case where thehole edge is closed. Thus, it is possible to hold the wires having alarge diameter or increase the number of the wires.

Out of the pair of through holes, the one through which the free endside of the band portion is first inserted may include a general partthrough which the free end side of the band portion is insertable and anextended part communicating with the general part and formed byextending the general part. According to such a configuration, the bandportion of the tie band is more easily inserted since an opening area ofthe early-inserted hole is extended by forming the extended part.

The extended part may be arranged at a side of the general part oppositeto a side toward which the wires are pulled as being tied by the tieband. According to such a configuration, at the time of tying, the bandportion moves toward the general part and the extended part foridentification becomes a large opening and the holding plate can belooked through from a top side or an underside. This enables an operatorto detect that the wiring harness has been tied in a proper state.

The extended part may be formed to have a curved hole edge. According tosuch a configuration, a situation where the band portion is caught bythe hole edge of the extended part for identification at the time ofinserting the band portion is unlikely to occur and a tighteningoperation can be smoothly performed.

DETAILED DESCRIPTION

Next, a specific embodiment of a wiring unit for automatic transmissionof the present invention is described with reference to the drawings.

A wiring unit U for automatic transmission of this embodiment is mountedin an automatic transmission of an automotive vehicle and in charge of apart of a control relating to a speed changing operation. As shown inFIGS. 1 to 3, the wiring unit U includes various electrical componentssuch as a ROM 1 and connectors, a wiring harness WH composed of aplurality of wires for connecting the electrical components and the liketo each other and a holding plate 2 made of metal for collectivelyholding these electrical components and wiring harness WH.

As shown in FIGS. 4 to 6, the holding plate 2 is formed by bending along metal plate material. The holding plate 2 is mounted on a casing ofthe unillustrated automatic transmission by bolts or the like, andformed with bolt insertion holes 3 penetrating at two positions nearopposite lengthwise end parts and at an intermediate part, i.e. at atotal of three positions in a shown example.

As shown in FIG. 1, an end connector 4 is arranged on a shown right endpart of the holding plate 2. On the other hand, a shown left end part ofthe holding plate 2 is forked into two directions, an intermediateconnector 5 connected to a control device and the like is arranged onone end part and the ROM 1 storing data relating to the speed changingoperation is arranged on the other end part. A mounting structure forthe ROM 1 is described in detail later. One end side of a wire 7 isconnected to the ROM 1 via a connector 6, and the other end side of thewire 7 is connected to the intermediate connector 5. The wiring harnessWH composed of the plurality of wires including this wire 7 is pulledout from the intermediate connector 5, and a main line thereof is laidalong a support surface 8 formed on the upper surface of the holdingplate 2. Branch lines are branched at a plurality of positions of themain line. A connector 9 connected to an unillustrated solenoid isconnected to each of the branch lines pulled out at shown four positionsout of those branch lines. Further, the branch lines pulled out at otherpositions are connected to the above end connector 4, and a groundterminal 10 is mounted on branch lines pulled out at further otherpositions and grounded by screwing a bolt into the bolt insertion hole 3arranged in the center out of the above bolt insertion holes 3.

As shown in FIG. 6, the holding plate 2 is horizontally formed to havesubstantially the same flat surface in a range from a mounted positionof the above end connector 4 to a longitudinal central part. A step 11is formed on a part of the holding plate 2 to the left of and adjacentto the part where the bolt insertion hole 3 is formed for grounding, anda part of the holding plate 2 to the left of the step 11 is one levellower. This one level lower part of the holding plate 2 serves as alow-level area 12, and a pressing portion 13 for regulating the lift ofthe main line part of the wiring harness WH is provided in thislow-level area 12.

The pressing portion 13 is integrally formed to the holding plate 2.Specifically, as shown in FIG. 8, the pressing portion 13 is composed ofa side piece 14 standing toward an upper surface side from onelongitudinal side edge of the support surface 8 and a pressing piece 15bent substantially at a right angle from the standing end edge of theside piece 14 and extending substantially parallel to the supportsurface 8, and is inverted L-shaped as a whole. A pressing surface 16for the wiring harness WH is formed on the inner surface of the pressingpiece 15. The pressing surface 16 is formed to have a predeterminedlength in a laying direction of the wiring harness WH and designed to beable to press the wiring harness WH in a surface contact state over acertain length range. Further, a height position of the pressing surface16 with respect to the support surface 8 is set to be substantially atthe same height as the upper surface of a high-level area 17 formed tothe right of the step 11. Note that, out of opposite longitudinal sideedges of the holding plate 2, the side edge opposite to the one wherethe pressing portion 13 is formed is cut to form a curved escapingrecess 18, and a tip part of the pressing piece 15 is located in theescaping recess 18 in a plan view as shown in FIG. 4.

The main line of the wiring harness WH is inserted through protectiontubes 19 (protecting members) at a plurality of separate positions. Theprotection tube 19 is also used at the part where the lift is regulatedby the above pressing portion 13. The protection tube 19 used here islonger than the pressing portion 13 so that coatings of the wires arenot damaged by the end edges of the pressing portion 13 (fracturedsurfaces may be edgy). The protection tube 19 is formed of a flexiblerubber material and the wiring harness WH is held by being somewhatpress-fitted between the pressing surface 16 and the support surface 8while being inserted through the protection tube 19. Note that, as shownin FIGS. 2 and 8, a projection structure T on the side of the casing isproximately located above the pressing piece 15 in a state where theholding plate 2 is mounted on the unillustrated casing of the automatictransmission.

Further, the wiring harness WH is tied by tie bands 20 and fixed to theholding plate 2 at opposite sides of the pressing portion 13 (protectiontube 19) in the longitudinal direction (see FIG. 1). As shown in FIG. 1,parts of the wiring harness WH tied with the tie bands 20 are bothexposed parts outside the protection tube 19. One of the tie bands 20located at the opposite sides of the pressing portion 13 is arranged inthe high-level area 17 proximate to the step 11 and the other isarranged in the low-level area 12 to the left of the pressing portion13. In this embodiment, the parts of the wiring harness WH fixed by thetie bands 20 are set at a plurality of positions besides the above partsat the opposite sides of the pressing surface 13. At any position, apair of through holes 21A, 21B are provided to penetrate through theholding plate 2. At all the positions of the pairs of through holes 21A,21B except at two positions (through holes 21A, 21B are arranged to theleft of and adjacent to the pressing portion 13 in FIG. 4 at oneposition out of these two positions), one through hole 21A has a closedhole edge and the other through hole 21B is formed by cutting the edgeof the holding plate 2 into a rectangular shape and open sideways. Asjust described, although a concept meaning not only a closed hole edge,but also including an open hole edge is applied to the through hole 21B,this does not eliminate at all a mode in which the pair of through holeshave both a closed hole edge.

The through hole with the closed hole edge out of the through holes 21A,21B of this embodiment is formed by uniting a rectangular area 22A(general part) and a substantially semicircular area 22B (extended partfor identification) as shown in FIG. 12. The reason of such a hole shapeis described in detail later. The tie band 20 is first described. Sincethe tie band 20 itself is known, it is only briefly described (see FIG.9).

The tie band 20 is made of synthetic resin and includes a flexible bandportion 23 and a lock portion 25 formed on one end side of the bandportion 23. A multitude of locking teeth 24 are formed in a sawtoothmanner over a predetermined length range only on one surface of the bandportion 23. On one end part of the band portion 23, the lock portion 25projects on an end part of a surface opposite to the one where thelocking teeth 24 are formed. An insertion opening 26 is formed topenetrate in a projecting direction in a central part of the lockportion 25 and the band portion 23 can be inserted into the insertionopening 26 with a free end side in the lead. Further, a locking claw 27capable of selectively locking an arbitrary locking tooth 24 isdeflectably provided in the lock portion 25.

The reason why two types of modes, i.e. a closed hole edge mode and anopen hole edge mode are set for the pair of through holes 21A, 21B is todistinguish into which of the through holes 21A, 21B the free end of theband portion 23 of the tie band 20 should be first inserted (see FIGS.11(A) and 11(B)). If the free end side of the band portion 23 of the tieband 20 is inserted into the pair of through holes 21A, 21B in a wronginsertion sequence, a pulling direction of the lock portion 25, i.e. apulling direction of the wiring harness WH as tying is performed isopposite to a proper direction (direction shown in FIG. 11(A)) and thewiring harness WH may interfere with surrounding members. However, ifthe tie band 20 is inserted in a correct insertion sequence, the wiringharness WH can be held by being pulled toward a retraction space freefrom interference with surrounding members. In the case of thisembodiment, the through hole with the closed hole edge is theearly-inserted hole 21A and the one with the open hole edge is thelater-inserted hole 21B. The semicircular area 22B of the early-insertedhole 21A is arranged on a side opposite to the side toward which thewiring harness WH is pulled (side indicated by an arrow shown in FIG.12) when being tied with the tie band 20. Thus, the band portion 23 islocated on the side of the rectangular area 22A of the early-insertedhole 21A and the side of the semicircular area 22B is wide open in astate where the wiring harness WH is properly tightened and fixed by thetie band 20. Thus, it can be visually confirmed that a tying operationof the tie band 20 has been properly performed if this wide semicirculararea 22B can be looked through in a plan view (or underside view) of theholding plate 2. Note that a tightening operation by the tie band 20 isperformed by pulling upwardly the band portion 23 having passed throughthe lock portion 25 using a tool, and a part of the band portion 23passed through the lock portion 25 is cut off by a cutter or the likeafter tightening.

As shown in FIG. 6, a crank portion 28 (see FIG. 4) extends via a partset to have a smaller height difference than the step 11 on a part ofthe holding plate 2 to the left of the low-level area 12. The upper endof a step wall 29 having a larger height difference than the step 11 isconnected to an extending end part of the crank portion 28 as shown inFIG. 6, and an intermediate connector mounting portion 30 continuouslyextends to bulge out sideways from the lower end of the step wall 29 asshown in FIG. 4. A reinforcing elongated projection 31 is provided alonga step direction in a range from the upper surface of the crank portion28 to the intermediate connector mounting portion 30, thereby enhancingthe bending rigidity of this part. Further, a supporting piece 34 isformed to stand upward on the intermediate connector mounting portion30, so that the intermediate connector 5 can be supported while beingsurrounded on three sides.

One side edge of the above step wall 29 is bent to the left of FIG. 4and a coupling piece 32 extends. An extending end part of this couplingpiece 32 is bent substantially at a right angle to an outer lateral sidevia a bent portion 38 and serves as a free end part. A holding portion33 for mounting the ROM 1 is formed on this free end part. As shown inFIG. 5, an opening 40 is formed in a central part of the holding portion33 near the bent portion so as not to interfere with a connecting partof the connector 6 to the ROM 1. Further, the bent portion 38 is formedwith a reinforcing rib 35 in a range from the coupling piece 32 to theholding portion 33 to enhance the bending rigidity of the holdingportion 33.

As shown in FIGS. 4 to 6, a plurality of swaging pieces 36 are formed tointegrally stand on the holding portion 33. In this embodiment, twoswaging pieces 36 are arranged on one side edge of the holding portion33 and one swaging piece 36 is arranged on the other side edge. Two ofthese swaging pieces 36 are arranged to face each other at oppositecorner parts of a tip side of the holding portion 33. As shown in FIG.4, a tip part of each swaging piece 36 serves as a somewhat narrowswaging portion 36A, which is inclined obliquely inwardly with respectto the side of a base portion 36B before being swaged to the ROM 1 (seeFIG. 6). Thus, after moving along the upper surface of the holdingportion 33 from the side of the bent portion 38, the ROM 1 is fixed tothe holding portion 33 by swaging the swaging portions 36A.

Further, in this embodiment, a positioning protrusion 37 projects on thelower surface (surface facing the holding portion 33) of the ROM 1 (seeFIG. 7). On the other hand, a rectangular receiving hole 39 (receivingportion) is formed to be open at a position of the holding portion 33near one side edge (side edge on which only one swaging piece 36 isarranged) and proximate to this swaging piece 36, and the ROM 1 can bepositioned with respect to the holding portion 33 before a swagingoperation by aligning and fitting the positioning protrusion 37 into thereceiving hole 39.

The wiring unit U of this embodiment configured as described above isassembled into the automatic transmission in a state where theelectrical components such as the ROM 1 and the connectors 4, 6 and 9and the wiring harness WH are assembled with the holding plate 2 andunitized in advance. Functions and effects of the wiring unit U of thisembodiment are as follows.

(1) In fixing the ROM 1 to the holding plate 2, the number of componentscan be reduced than before since each swaging piece 36 is integrallyformed to the holding plate 2 and the ROM 1 can be directly fixed to theholding plate 2. Further, the ROM 1 is positioned with respect to theholding portion 33 by aligning and fitting the positioning protrusion 37into the receiving hole 39. Since the swaged positions for the ROM 1 arespecified at proper positions in this way, the swaged positions do notvary. Further, in performing the swaging operation for the ROM 1, abending force acts on the holding portion 33 with the bent portion as acenter. However, since the bending rigidity of the bent portion isenhanced by the reinforcing rib 35, a situation where the holding plate2 is deformed as swaging is performed is avoided.

(2) The lift of the wiring harness WH is regulated by a simplestructure, i.e. the pressing portion 13 integrally formed to the holdingplate 2. Thus, in a place where a certain structure is present above thewiring harness WH, the interference of the wiring harness WH and thestructure can be avoided by arranging the pressing portion 13. Further,since the pressing portion 13 presses the wires in a predetermined rangeextending along the laying direction by the pressing surface 16, aninterference avoiding area can be ensured in a wide range as comparedwith local pressing such as that by the tie bands 20. Further, if thewiring harness WH is passed through the pressing portion 13 after beinginserted through the protection tube 19, a situation where the wirecoatings are damaged can be reliably avoided even if the end edges ofthe pressing portion 13 are edgy. Furthermore, since the pressingportion 13 is open sideways in this embodiment, an operation ofinserting the wiring harness WH can be easily performed. Furthermore, inthis embodiment, by arranging the pressing portion 13 in the low-levelarea 12 for the wiring harness WH passing through two areas with aheight difference where the lift easily occurs, the lift can beeffectively regulated. Further, since being forcibly bundled by thepressing portion 13, the wiring harness WH conversely tends to easilyspread at the opposite sides of the pressing portion 13. However, sincethe wiring harness WH are tightened and fixed by the tie bands 20 at theopposite sides of the pressing portion 13 in this embodiment, the liftof the wiring harness WH can be regulated in a wider range by thecooperation with the pressing portion 13.

(3) In the through holes 21A, 21B through which the band portion 23 ofthe tie band 20 is to be inserted, the early-inserted hole 21A and thelater-inserted hole 21B have different hole edges and can be easilydistinguished in external appearance, wherefore the insertion sequenceof the band portion 23 through the through holes 21A, 21B can becorrectly selected. Thus, the lock portion 25 and the wiring harness WHcan be reliably pulled toward the space where the interference with thesurrounding members can be avoided. In addition, since the semicirculararea 22B is formed on the side opposite to the one toward which thewiring harness WH is pulled concerning the positional relationshipbetween the semicircular area 22B and the rectangular area 22A of thethrough hole 21A, the band portion 23 can be located in the rectangulararea 22A and the semicircular area 22B can be largely open. Therefore,an operator can detect that the tying operation has been properlyperformed by visually confirming such an open state in theearly-inserted hole 21A. Further, since the extended part of theearly-inserted hole 21A is formed into a rounded shape (semicircularshape), the band portion 23 is unlikely to be caught at the time ofinsertion and the tightening operation can be smoothly performed.

The present invention is not limited to the above described andillustrated embodiment. For example, the following embodiments are alsoincluded in the technical scope of the present invention.

The number and arrangement of the swaging pieces 36 are not limited tothose in the above embodiment and as many swaging pieces may be arrangedon the opposite side edges of the holding portion 33.

Although a target to be fixed by the swaging pieces 36 is the ROM 1 inthe above embodiment, it may be another electrical component and may be,for example, a sensor, a connector or the like.

Although the positioning protrusion 37 is formed on the side of the ROM1 and the receiving hole 39 is formed on the side of the holding plate 2in the above embodiment, a reverse relationship may be adopted. Further,the receiving portion for the positioning protrusion 37 needs not be athrough hole like the receiving hole 39 and may be a non-penetratingrecess.

Although the holding portion 33 is set on the free end part of theholding plate 2 in the above embodiment, it may be provided at anintermediate position of the holding plate 2. If such a configuration isadopted, the reinforcing rib 35 can be omitted even if the holdingportion 33 is arranged via a step.

Although the pressing portion 13 is arranged only at one position in theabove embodiment, it may be arranged at a plurality of positions. Insuch a case, the pressing portion 13 may be arranged on one side edge ofthe holding plate 2 and other pressing portion(s) 13 may be arranged onthe other side edge and, further, the pressing portions 13 may beshifted in position in the longitudinal direction.

Although, out of the pair of through holes 21A, 21B, the early-insertedhole 21A is formed larger than the later-inserted hole 21B in the aboveembodiment, it may be conversely formed smaller. Further, the pair ofthrough holes 21A, 21B have only to be distinguishable in externalappearance and the individual hole shapes do not matter.

Although the wiring harness is inserted through the protection tubes 19in the above embodiment, flexible sheet materials may be wound aroundthe wiring harness for protection.
